Is Fiber Glass Good for Acoustics?

When it comes to soundproofing, ensuring you have the most effective materials in your property is integral. However, it’s not always easy to find these materials, which of course begs the question: which materials are the best for soundproofing? While this isn’t always clear, there are several awesome materials you could consider, and just one option is fiber glass. But what is fiber glass anyway, and is it good for soundproofing? We’ve outlined some of the key things you need to know to help you find out more about the properties of fiber glass and how it could work for your property.

What is Fiber Glass?

What is fiber glass? Despite what the name would suggest, fiber glass isn’t actually a form of glass, but it is actually a type of plastic. However, the plastic is reinforced through glass fibers, thus leading to the name. Overall, fiber glass generally uses a very fine woven structure which helps contribute to its numerous insulating properties.

It is most commonly available as a sheet, but if you have been looking for fiber glass for acoustic purposes, acoustic panels made from fiber glass can also be available.

Is Fiber Glass Good for Acoustics?

At this point, we’ve mentioned fiber glass for acoustics – but how good actually is it? Well, it’s not always directly clear how effective fiber glass is for acoustic purposes since it’s not directly designed with this in mind. However, fiber glass offers numerous insulating properties for heat control, so it’s not a huge stretch to assume that fiber glass might also be good for sound control.

But is this the case? Well, yes! While fiber glass isn’t the most effective material on the market for sound absorption, it’s very close – all the while delivering almost unbeatable value for money. It’s also easy and practical to work with, making it easy to see why so many people use fiber glass for their property’s sound insulating needs.

Overall, when considering the noise reduction coefficient, fiber glass is exceptionally effective. It scores (as standard) around 0.90 on the scale out of a maximum of 1.0. As such, there’s genuinely not much room for fiber glass to improve in terms of its sound absorption properties!

The only real drawback here is that fiber glass isn’t overly effective for blocking out sound. As such, if you need a completely soundproof room, it may be worth considering a thick wall of fiber glass, or pair it with other sound absorbing options.

Remember: you don’t need to be limited only to your property’s walls, either. You can also use fiber glass on the ceilings and floors in your property, making it even more effective.
